Learn how to build a dynamic JavaScript line chart with conditional styling using a custom PaletteProvider in SciChart.js.
In this tutorial, you'll discover how to highlight values above a threshold, handle gaps in data, and apply metadata-driven styling without disrupting chart continuity. SciChart.js delivers high-performance WebGL rendering, making it ideal for monitoring dashboards, anomaly detection systems, IoT platforms, and real-time analytics applications.
What You'll Learn:
✅ How to create a line chart in JavaScript
✅ How to implement a custom PaletteProvider
✅ How to apply conditional styling based on data values
✅ How to handle gaps and missing data using metadata
✅ How to add threshold lines and annotations
✅ How to enable zoom, pan, and reset interactions
Topics Covered:
- SciChartSurface setup
- FastLineRenderableSeries configuration
- Custom PaletteProvider implementation
- Metadata-driven styling
T- hreshold annotations
- Chart interactivity and navigation
Frequently Asked Questions
Q: What is a PaletteProvider in SciChart?
A: A PaletteProvider enables dynamic styling of chart elements based on data values or metadata, making it easy to apply conditional colouring to lines, points, and fills.
Q: How do you handle gaps in a line chart?
A: Gaps can be managed using metadata rather than NaN values, giving developers greater control over how individual segments are rendered and styled.
Q: How do you highlight thresholds in charts?
A: SciChart allows you to combine conditional styling with annotations such as HorizontalLineAnnotation to visually indicate threshold levels and critical values.
Use Cases
- Monitoring dashboards
- Anomaly detection systems
- IoT and sensor data visualisation
- Real-time analytics applications
